IMPRQVEMVENT IN CALL-BELLS.

Specification forming part cf Letters Patent No. 147,486, dated February17, 1874; application tiled December 2, 1873.

of a hand-wheel, so applied and arranged in` connection therewith as tooperate the hammers and ring the bell or bells when the said wheel isrotated, or partly rotated, upon its axis and in the arrangement of awheel between two bells placed mouth to mouth; and in other novelfeatures, hereinafter described.

Figure 1 of the accompanying drawing is an` elevation of my improvedbell, Viewed on a line with the periphery of the hand-wheel. Fig. 2 is alongitudinal section of the same; and Fig. 3 is a transverse view onlines :v of Figs. l and 2, one of the bells being removed, and the axialrod and one of the supporting-arms being in section.

As shown in the drawings, A A are two liemispherical or gong-shapedbells, mounted on, and secured immovably to, the cranked axle rod B,passing centrally through them, and which is also secured immovably tothe curved and flexible supporting-arms C C, which rise from the base orstandard D. Upon the center of the axial rod B is mounted the handwheelE, which is arranged to revolve thereon within the bells between themouths of the same, the handles a a of the wheel passing between the'mouths and projecting beyond the exterior of the bells, as shown. Thebells are arranged, preferably, so close together that space enough isleft for the handles only of the lwheel to pass through and allow thesame to The periphery of the wheel lies within the bells, as shown, andclose to the interior sides of the same, so that the small space4between the mouths of the two bells is thus closed, and the interiormechanism concealed from view. The axial rod B is cranked, as shown inFig. 27 and in the cranked portions are pivoted small rock-shafts orpins k k, from which depend the hammers f f and cranks or cams ce. Thecams e e project toward the hub of the wheel, and are alternately struckby projecting pins g g on the hub of the wheel when the same is rotatedand are oscillated thereby, causing the hammers to strike and ring thebells. This will be understood on reference tol Fig. 2 and to Fig. 3,where the hammer is shown upon the point of striking.

Instead of the rock-shafts k k spring-wire may be used for thehammer-rods, and the same actuated by the direct contact of the pins gg,- anda straight axial rod may be used in lien of a cranked one.

A portion on the lower side of each bell is cut away, as shown at Z l,Figs. 1,2, and 3, forming an open space, in which the hammers swing andring the bell by striking against the edges of the projecting portion;but, if preferred, the hammers may be arranged to swing inside thebells, and the slot or opening be dispensed with. In vthe former case,the base may be extended upward in an ornamental lioral or other design,so as to cover and conceal this open space, as represented by the dottedlines in Fig. l.

By the use of the recesses the hammers are made to strike the bell uponits edge, andV thereby produce a clearer sound. They also allow thehammers a larger swing, so that the stroke will be more effective; and,by striking upon the edges of the bells, the same are not so liable tobe fractured or injuredl by wear as if struck upon the inner surface.

To ring the bell it is only necessary to move one of the handles a awith the finger when the wheel will then revolve, and its momentum willvibratethe hammers and keep the bell ringing for several seconds.

In this way I produce a bell of extremely unique character andornamental appearance7 and of very simple and facile operation.

I do not wish to conne myself to the particular mechanism herein shown,by which the hand-wheel is made to operate the hammers, as other methodsof accomplishing this result may be readily devised; and the wheel andhammers may be connected with each other in a positive manner byeeeentries, cams, cranks,

or other devices. Nor do I wish to confine myself 'to the particularform of bell shown; but

That I claim a filly-invention, and desire to secure by Letters Patent',is

l. In combination with two bells, arranged mouth to mouth7 a wheelarranged to rotate in a plane parallel with. the month of' the bells tooperate the striking mechanism for sounding the bells.

2. In eon'rbination with one or more bells7 awbeel, or its equivalent,operating,` on its rotation directly on the striking mechanism,substaniially as and for the purpose set forth.

il. In combination with the bell or bells a-nd and their strikingmechanism arranged within them, a wheel, or its equivalent, arrangedwithin, or partially within, the bell or bells to operate the stri king`mechanism` when rotated7 set forth.

4. In eombination with J(he wheel E, or its equivalent, bell or bells AA, rod B, and hammers f f, the pins g g, eanis e e, and rods k 7.',substantially as and for the purpose set forth.

In Witness whereof I have hereunto signed my name in the presence of twosubscribing' witnesses.
